A power roller assembly for painting or coating surfaces is provided having a roller applicator rotatably mounted on a roller applicator support arm through which paint under pressure is supplied to the interior of the roller applicator by means of a control valve communicating with a source of paint under pressure. The paint is distributed longitudinally along the interior of the roller applicator by means of a tubular-shaped manifold co-axially mounted and spaced from the roller applicator axle. The paint in the interior of the roller applicator is pushed longitudinally back and forth thereacross by means of an auger-like spiral mounted co-axially with the roller applicator for rotation therewith.
